# This awk script munges the POT file into something that the
# Translation Project's tools can cope with.  Aparrently it isn't enough
# that the file is in a correct format, it has to be in the default
# (empty msgstr) format coming out of xgettext, and unindented, too.
#
# The English translation is thus shifted into the leading comment for
# translator's reference.
#
# The leading header comment is also mangled to add the "optional"
# Project-Id-Version and POT-Creation-Date lines which their system
# can't seem to cope without.
